Yeah it looks like an original problem with the game so then I have to ask If they even did a decent job at beta testing. What was their process I wonder but I can come to the conclusion that this game never should have been released. If it was any other product it would have been refunded with a full refund. We have to start holding video game companies accountable and I don't just mean not purchasing a DLC.
It must be. I have a plain vanilla game. No "bonus" DLC, and the 360 is not connected to the internet (I only connect it to DL patches, then disconnect. I havent connected since I got this game.) So my copy is as-is from the original disk with no patches of any kind. I installed to the 360 HD.
I got the bug during the Come fly with me quest. If I load the game in the basemant while talking to Harlan it loads fine. I saved right before pressing the launch button, that save is corrupt. Somewhere in between that short period the bug popped up. Everything after that is bad. I didn't pick up the space suit either, so much for that theory.
The original FO3 game gave me problems too. In the "Waters of life" quest everytime I tried to complete the quest in the rotunda after talking to your father the game would freeze when going through a door. Because of this I could never complete the main quest in that game either.
They need a new engine. The Fallout engine they use is a piece of bug infested junk. It don't work. I think they need to recall this thing. They may say it is "isolated" but I doubt it. They should know that not everyone with the bug will sign up and post here or call them with the issue.
Hey I heard there is going to be new DLC available! Oh wait my original game I bought doesn't even work, never mind...
